KNOT FOR NET FABRICS.

SPECIFICATION forming part of Letters Patent No. 483,291, dated September 27, 1892.

Application filed January 29, 1892. Serial No. 419,698. (No model.) Patented in Germany July 7, 1891, No. 60,248, and in Italy November 12, 1891, No- 30,606.

To all whom it may concern:

Be it known that I, ROBERT SEMMLER, Sn, a subject of the Emperor of Germany, and a resident of Siegmar, Saxony, Germany, have invented certain Improvements in Knots for Net Fabrics, (patented in Germany July 7, 1891, No. 60,248, and in Italy November 12, 1891, No. 30,606,) of which the following is a specification.

The object of the present invention is to make a net fabric in which the threads will be so connected that each will be secured to the other by a separate knot, thus holding the connections immovable and greatly increasing the strength and durability of the fabric.

In the accompanying drawings, forming part of this specification, Figures 1, 2, and 3 are views explanatory of the ordinary method .of connecting the threads of a net fabric, and Figs. 4 to 7 are views illustrating the manufacture of net fabrics according to my improvemen ts. Figs. 8 to 11 illustrate a slightlydifferent method of arranging the threads, in which the coil passes in front of instead of to the rear of the thread; and Fig. 12 is a detail View of the fabric.

The knot ordinarily made by hand and machine tying has the threads before being drawn taut disposed as shown in Fig. 1, and neither forming a knot, such as shown in Fig. 2. In Fig. 1 thread 0/. forms an open and thread I) a cross loop, the former lying in the latter, one portion b of which lies in the open loop formed by thread a. In such instance if both threads are drawn tight a knot is made, (ordinarily known as a net or weavers knot but if only the thread a is drawn and pulled straight the'loop formed by thread a is pulled out of that formed by thread I), and the thread of the latter is also carried along, as shown in Fig. 3. The knot formed by the thread I) can be shifted on thread a, and consequently the connection between a and Z) is not sufficiently tight or strong.

My invention obviates the objections incident to the arrangement described by providing an immovable connection formed of a double knot. The method of forming said improved connection is illustrated in Figs. 4 to 7.

To provide the fabric threads 0 d with double knots m a, as shown in Fig. 12, the threads 0 d are passed in opposite directions around the upper pair 1 3 of a series of four pins 1, 2, 3, and 4, each thread being then brought alongthe outer side of the pins, then passed around a lower pin 2 4, behind 1tself, and each of them behind the corresponding portion of the adjacent thread, Fig. 5, then each through the loops say of the other thread, as indicated at 0 cl, then across the led portion of the other thread, Figs. 5 and 6, and finally each passes to the rear through its own loop in the construction shown in Fig.6, and each thread forming a loop, as shown in Fig. 7. In such an arrangement by drawing the threads f g h 7. each loop can be closed to form a real knot equal to that shown in Fig. 2, and both knots are so interlaced that the connection is absolutely immovable.

As shown in Fig. 5, the threads 0 d may be led so that they eventually pass to the rear of their inner parallel portions, and finally forward through the loops no 3 It will thus be seen that I do not limit myself to the particular way of leading the threads.

In Figs. 8 to 11 the threads 0 and (Z pass around the pins, and instead of entering the loops as 3 pass around each other, as shown in Fig. 9. They then cross and enter the loops :1; y, as shown in Fig. 10, and the knot, as shown by Fig. 11, is formed by pulling the threads.

Having now particularly described and ascertained the nature of the said inventionand in what manner the same is to be performed, I declare that what I claim is- 1. The method of connecting the threads in net fabrics, 20., consisting in arranging and interlacing the said threads to provide each with a loop capable of forming a separate knot and drawing said loops taut to establish an immovable connection comprising a knot for each thread, substantially as set forth. 7

2. A net fabric having its threads joined by two independent and interlaced knots, affording an immovable connection for each thread with the other, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.
